Background Depot medroxyprogesterone acetate (DMPA) contraceptive use is associated with an increased risk for Chlamydia infection. However, prior studies inadequately account for potential differences in sexual behavior between users of DMPA and users of other contraceptive methods. In this study we compare sexual risk-taking behavior in women using DMPA to women using oral contraceptive pills...

Background: This retrospective study evaluated the effect of profound pituitary suppression with oral contraceptive pill (OCP) pretreatment in gonadotropin-releasing hormone (GnRH) antagonist cycles stimulated with recombinant follicle stimulating hormone plus highly purified human menopausal gonadotropin. Methods: The analysis included women aged 20-46 years (N=318) who utilized OCP pretreatme...

During the initial phase of space trajectory planning and optimization, it is common to have to solve large dimensional global optimization problems. In particular continuous low-thrust propulsion is computationally very intensive to obtain optimal solutions. In this work, we investigate the application of machine learning regressors to estimate the final spacecraft mass mf after an optimal low...

Fluorescence microscopy is commonly used to investigate disease progression in biological tissues. Biological tissues, however, are strongly scattering in the visible wavelengths, limiting the application of fluorescence microscopy to superficial (<200µm) regions. Optical clearing, which involves incubation of the tissue in a chemical bath, reduces the optical scattering in tissue, resulting in...

The concluding chapter of this part of the book discusses several flight control implementation examples that integrate Matlab/Simulink within the open control platform (OCP) framework (described in Chapters 4 and 5). A public domain version of an F-16 aircraft model, available as a Simulink block with OCP distribution 1.0, is used for illustration. The first example is a linear quadratic regul...

OBJECTIVE To investigate the microbial and cytopathological changes and genital symptoms in oral contraceptive pill (OCP) and intrauterine contraceptive device (IUCD) users. METHODS Included in the study were 34 women using OCP and 34 women using IUCD for 24 to 36 months period and 34 women as control group. We conducted the study between March to September 2005 in Antakya Maternity Hospital,...

4-(N-hydroxyphenyl) retinamide (4-HPR) and the oral contraceptives (OCP) are currently being used alone, and in combination, for the prevention of ovarian cancer. However, the mechanism of their effects has not been studied. Non-human primate models are ideal for studying the role of these and other drugs for cancer chemoprevention because of the genetic similarity between primates and humans i...

This paper argues that phonetic naturalness and unnaturalness can interact within a single grammatical system. In Japanese loanword phonology, only voiced geminates, but not voiced singletons, devoice to dissimilate from another voiced obstruent. The neutralizability difference follows from a ranking which Japanese speakers created on perceptual grounds: IDENT(voi)Sing » IDENT(voi)Gem. On the o...

Genetic studies have demonstrated that osteoclasts are essential for focal erosion of bone and cartilage as a consequence of chronic pro-inflammatory cytokine production (TNF, IL-1) in inflammatory arthritis. In these inflamed joints, mature osteoclasts differentiate from circulating osteoclast precursors (OCPs) in response to local increased production of RANKL and pro-inflammatory cytokines. ...
